Power Grid Construction Project Subcontract Cost Control System Design And Implementation

The project subcontract management is an important part of project management, itplays an increasingly important role in project management. To use of projectmanagement tools fully, and to improve project management capabilities, it is necessaryto establish a sound sub-system. Project subcontractors is an inevitable trend of theobjective conditions of the modern market and corporate development.Commence by the actual needs of the Sichuan Electric Power Transmission andDistribution Construction Company grid project subcontract cost management, thisthesis researches the background, purpose, significance and development status at homeand abroad of the Sichuan Power Transmission and Distribution Construction Companygrid project construction subcontractor cost management system, expounds thetechnology and future development trends, introduces the Java EE architecture, Oracledatabase platform, the Tomcat server which will be used. This thesis discusses anddesignes a system based on B/S system module, and finally raises the Sichuan PowerTransmission and Distribution Construction Company grid project constructionsubcontractor cost management system solution.The system uses object-oriented analysis and design techniques, based on Java EEarchitecture design and development, supports N-tier service model to meet the full JavaEE1.4version of the standard, the system has a good framework and flexibility. Thisreduces the burden on the server, brings faster response speed and reduces the waitingtime, while providing a friendly user-friendly operator interface. Based on the actualneeds of the Sichuan Power Transmission and Distribution Construction Company gridproject construction subcontractor cost management to start to deal with the access tothe data and take appropriate measures to achieve the purpose of the Transmission andDistribution Construction Company grid project construction subcontractor costmanagement to sub-contract price as a starting point, establishes the review of theprogress payment of subcontracting charges, strengthens the management of change,claims and settlement, and relies on the duties and powers set and a variety of reportgeneration and allow staff to keep abreast of the overall project labor subcontracting costs and dynamic conditions, the timely detection of problems to take correctivemeasures to promote labor subcontracting cost management standardization.
